Estudo do envelhecimento de pseudoboehmita
(Associação Brasileira de CerâmicaBento Gonçalves, RS, 2014-05-18)
Neste trabalho pseudoboemita foi sintetizada pelo processo sol-gel. Estudou-se a influência das variáveis temperatura de envelhecimento (temperatura ambiente e 130° , adição de álcool polivinilico na solução precursora ...
ZnO-TiO2 composite formed by mixed oxides via polyol
(Trans Tech Publications Ltd, 2012-01-01)
Among the researches on preparation and test of nanostructured materials, titanium dioxide and zinc oxide have been the most frequent studied oxides. In order to extend their properties, composites have been prepared using ...

Photoluminescence of the Eu-doped thin film heterojunction GaAs/SnO2 and rare-earth doping distribution
(Iop Publishing Ltd, 2015-01-01)
Tin dioxide (SnO2) thin films doped with Eu3+, are deposited by the sol-gel-dip-coating process on top of GaAs films, which is deposited by resistive evaporation on glass substrate. This heterojunction assembly presents ...
Waveguide features in self-patternable amine functionalized organic-inorganic hybrids
(Ieee, 2007-01-01)
We report the use of organic-inorganic sol-gel derived poly(oxyehylene)/siloxane hybrid doped with methacrylic acid modified zirconium (IV) n-propoxide for the fabrication of low cost waveguldes trough direct UV laser ...
